Description

Technical Field

[0001] This utility model relates to the field of safety and air defense systems for high-voltage electrical equipment, and in particular to a power equipment defect detection device based on infrared images. Background Technology

[0002] With the continuous expansion of the power grid, the number of power transmission and transformation equipment is increasing daily, leading to growing pressure on operation and maintenance. Infrared image detection is an effective means of condition monitoring for power transmission and transformation equipment. As a non-contact measurement technology, it can detect external and internal defects of power transmission and transformation equipment without affecting its operation, and features safe operation and convenient testing. Therefore, the "People's Republic of China Electric Power Industry Standard (DL / T 393-2010): Test Procedures for Condition-Based Maintenance of Power Transmission and Transformation Equipment" clearly states that "all normally operating power transmission and transformation equipment must undergo infrared image detection annually," and that "all routine tests of electrical equipment must include infrared thermal imaging detection." However, traditional detection devices are installed in a fixed location, making temporary and rapid deployment impossible. The publication number CN107635116A, titled "...", is relevant here.

[0003] A patent for an invention entitled "Video Monitoring System for Power Transmission and Transformation Equipment" discloses a video monitoring system for power transmission and transformation equipment, including a video monitoring pole, a remote communication device, a line voltage stabilization device, and a power transmission and transformation equipment container. LED alarm lights are installed on the outer wall of the video monitoring pole, which is connected to the power transmission and transformation equipment housing via a nut through-hole. A remote communication device is installed on the upper surface of the power transmission and transformation equipment housing, and a power transmission and transformation equipment container is installed at the front end of the housing. An automatic heating device is installed below the central information processor, and a video acquisition and processing terminal is installed inside the housing. A video analysis module is connected to a network transmission module via wireless signal data, and the network transmission module interacts with a remote monitoring station via wireless satellite signals. This power transmission and transformation equipment video monitoring system is pre-installed by workers, making it difficult to relocate and conveniently deploy later. It is not suitable for installation while the power transmission and transformation tower is energized, for deployment in emergency situations, or for temporary deployment. Utility Model Content

[0004] In view of the shortcomings of the background technology, the technical problem to be solved by this utility model is to provide a power equipment defect detection device based on infrared images. This device can be flexibly deployed by drones, adaptable to temporary deployment for quick and convenient retrieval and placement, and adaptable to rapid deployment in emergency situations.

[0005] Therefore, this utility model is implemented using the following technical solution:

[0006] An infrared image-based power equipment defect detection device includes a camera monitoring device suitable for drone gripping and a positioning and clamping platform installed on the top of a power transmission and transformation tower. The monitoring device includes a power supply, a main unit, and an infrared camera. The infrared camera is rotatably mounted on the top of the main unit. The positioning and clamping platform includes an upwardly protruding conical clamping end. The bottom of the camera monitoring device has a conical clamping groove that matches the conical clamping end. The conical clamping groove is sleeved on the conical clamping end and magnetically fixed.

[0007] Preferably, the top of the conical snap-fit ​​groove and the top of the conical snap-fit ​​end are respectively provided with a pair of magnets that can attract each other.

[0008] Preferably, a lower annular magnetic strip is distributed around the bottom edge of the conical snap-fit ​​end on the positioning snap-fit ​​platform, and an upper annular magnetic strip matching the lower annular magnetic strip is distributed around the edge of the conical snap-fit ​​groove at the lower part of the camera monitoring device. After the conical snap-fit ​​groove is fitted onto the conical snap-fit ​​end, the upper annular magnetic strip and the lower annular magnetic strip attract each other, and the top of the conical snap-fit ​​groove and the top of the conical snap-fit ​​end attract each other.

[0009] Preferably, the power source is a battery power supply system, which is installed inside the main unit. A solar panel is fixed on the side of the main unit, and the solar panel can convert solar energy into electrical energy to charge the battery.

[0010] Preferably, the positioning card receiving platform has a horizontally set QR code platform. The QR code platform is set with QR code information containing the coordinates of the card receiving end. The drone scans the QR code to obtain the coordinate information and performs the deployment operation.

[0011] Preferably, the infrared camera has a gripping handle on top, the gripping handle having a gripping handle and a through-grip gripping slot.

[0012] The beneficial effects of adopting the above technical solution are as follows: The power equipment defect detection device of this utility model is easy to deploy using drones. It only requires a positioning and clamping platform to be set up on the top of the transmission and transformation tower in advance. The conical clamping groove at the bottom of the camera monitoring device is sleeved on the conical clamping end. The conical sleeve structure of the two facilitates the guiding sleeve under the hoisting of the drone. Then, the annular magnetic strip on the bottom edge of the conical clamping end and the upper annular magnetic strip around the edge of the conical clamping groove are magnetically attracted and fixed. At the same time, the top of the conical clamping groove and the top of the conical clamping end attract each other. Through the above triple positioning and magnetic fixation structure, the power equipment defect detection device can be quickly installed and can be stably set up. This enables the rapid and flexible deployment of the camera monitoring device on the top of the transmission and transformation tower, which is conducive to meeting the deployment needs in temporary or emergency situations.
